Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIGS. 1 through 9 illustrate the graduated sight glass container of the present invention indicated generally by the numeral 10.
The graduated sight glass container 10 of the present invention is shown in FIG. 1. In this figure, the graduated sight glass container 10 is being used by a person 12 to deposit oil into an opening 14 for the oil tank 16 in an engine 18 of a vehicle 20. The graduated sight glass container 10 includes a spout 22 which is able to be positioned close to and directly over the opening 14 through which the contents of the graduated sight glass container 10 will be deposited prior to pouring.
An enlarged view of the graduated sight glass container 10 is illustrated in FIG. 2. This view illustrates the user 12 holding the graduated sight glass container 10 in one hand 24 and placing the spout 22 at the opening through which the contents of the graduated sight glass container 10 will be poured. The graduated sight glass container 10 is shown in its upright position in dashed lines. The spout 22 of the graduated sight glass container 10 is able to fit into the opening 14 and thus allow dispensing of the contents of the graduated sight glass container 10 with a minimal amount of spillage.
An exploded bottom perspective view of the graduated sight glass container 10 is illustrated in FIG. 3. This figure illustrates use of the graduated sight glass container 10 for retaining motor oil therein as is indicated by the label 24. The spout 22 is positioned to extend from an indented section 26 of a first side 28 of the container 10. The spout 22 has a length not greater than a length of the indented section 26 and therefore does not extend past the first side 28.
As can be seen from FIG. 3, the graduated sight glass container 10 is preferably in the shape of a rectangle and includes a first graduated scale 30 extending along a second side 32 thereof. At least a portion of the second side 32 is preferably made of a translucent material allowing the user to view the contents of the graduated sight glass container 10 and determine the amount of substance contained therein using the first graduated scale 30. The first graduated scale 30 includes indicia 38 printed therealong, the indicia being indicative of the volume of the container 10 at predetermined heights along the length of the second side 32. The indicia 38 allows the user to determine the amount of substance within the graduated sight glass container 10 when in a vertical upright position. The indicia 38 is provided to indicate the volume of the container in both ounces 42 and milliliters 44. The measurement of the volume using ounces and milliliters is for purposes of example only. The indicia may use any other unit of measurement such as cubic centimeters, cups, pints, quarts, gallons, etc. Measurement of the volume of the contents when the graduated sight glass container 10 is in a vertical position will be described in greater detail hereinafter with specific reference to FIGS. 6 and 7.
A second graduated scale 34 extends along a base side 36 thereof. At least a portion of the base side 36 is preferably made of a translucent material allowing the user to view the contents of the graduated sight glass container 10 and determine the amount contained therein using the second graduated scale 34. The second graduated scale 34 includes indicia 40 printed therealong, the indicia being indicative of the volume of the container at predetermined heights along the length of the base side 36. The indicia 40 allows the user to determine the amount of substance within the graduated sight glass container 10 when in a horizontal position, e.g. when the contents are being dispensed. The graduated scale 34 also allows the user to measure an amount of substance being dispensed. The indicia 40 is provided to indicate the volume of the container in both ounces 46 and milliliters 48. The measurement of the volume using ounces and milliliters is for purposes of example only. The indicia may use any other unit of measurement such as cubic centimeters, cups, pints, quarts, gallons, etc. Measurement of the volume of the contents when the graduated sight glass container 10 is in a horizontal position will be described in greater detail hereinafter with specific reference to FIGS. 8 and 9.
A side view of the graduated sight glass container 10 is shown in FIG. 4. From this figure it is seen that the graduated sight glass container 10 is preferably rectangular in shape and includes an indented section 26 on the first side 28 thereof. Extending from the indented section 26 and having a length substantially equal to that of the indented section 26 is the spout 22. The spout 22 thus extends no further than the first side 28. The spout 22 further includes a cover 50 releasably engaged therewith for sealing the graduated sight glass container 10 when not in use. The cover 50 may be releasably connected to the spout 22 by any known means such as a threaded engagement between a thread spiraling around an inner side of the cover 50 and a thread spiraling around an outer side of the spout 22, a stopper arrangement wherein the cover 50 has a circumference substantially equal to the circumference of the spout 22 and fits within the spout 22, etc.
Surrounding the spout 22 is a pool 52 as can be seen in FIG. 5. The spout 22 is shaped to fit within a desired opening when tilted for dispensing the contents therein such that the rim of the opening is received within the pool 52. The placement of the spout 22 in the opening during dispensing eliminates the possibility of spilling the contents. The graduated sight glass container 10 may also include a label 24 for identifying the contents.
FIG. 5 illustrates the graduated sight glass container 10 of the present invention looking at the first side 28. This view shows the spout 22 extending from the indented section 26 and the cover 50 positioned to selectively seal the spout 22 preventing the contents from being dispensed therethrough. Surrounding the spout is the pool 52, providing a space between the spout 22 and a base side 54 of the indented section 26. This allows the spout 22 to extend into the opening when dispensing the contents of the graduated sight glass container 10.
FIGS. 6 and 7 illustrate use of the first graduated scale 30 for measuring the volume of substance filling the graduated sight glass container 10. FIG. 6 illustrates a substance 56 within the graduated sight glass container 10 filling approximately two thirds of the graduated sight glass container 10. The amount of the substance 56 within the container measures up to the line of the indicia 38 indicating 20 ounces and slightly less than 600 milliliters. When an amount of the substance 56 is dispensed from the graduated sight glass container 10, the level of the substance will decrease as illustrated in FIG. 7. This figure indicates that an amount of the substance 56 has been dispensed from the graduated sight glass container 10 until an amount approximately equal to 3 ounces and slightly less than 100 milliliters remains within the graduated sight glass container 10. Thus, after dispensing a desired amount of substance therefrom and placing the graduated sight glass container 10 in a vertical position, a user is able to determine when the graduated sight glass container 10 is empty and also determine how much of the contents has been dispensed.
FIGS. 8 and 9 illustrate the second graduated scale 34 extending along the base 36 of the graduated sight glass container 10. When viewing the second graduated scale 34, the graduated sight glass container 10 is in a horizontal position for dispensing the contents therein. FIG. 8 illustrates a substance 58 within the graduated sight glass container 10 filling approximately two thirds of the graduated sight glass container 10. The amount of the substance 58 within the container 10 measures up to the line of the indicia 40 indicating slightly less than 20 ounces and slightly less than 600 milliliters. When an amount of the substance 58 is dispensed from the graduated sight glass container 10, the level of the substance will decrease as illustrated in FIG. 9. This figure indicates that an amount of the substance 58 has been dispensed from the graduated sight glass container 10 until an amount approximately equal to 5 ounces and slightly more than 200 milliliters remains within the graduated sight glass container 10. When using the second graduated scale 34 an amount of the contents can be measured during dispensing to provide an accurate measurement of the amount which has been dispensed. The user may thus is able to dispense a desired amount, ceasing the dispensing of the contents when the desired measurement is reached.
The operation of the graduated sight glass container 10 will now be described with reference to the figures. In operation, the graduated sight glass container 10 is filled with a desired substance and the cover 50 is positioned to releasably seal the substance therein. When it is desired to dispense the substance from within the container 10, the cover 50 is removed.
Prior to dispensing, the user views the first graduated scale 30 to determine how much of the substance is contained within the container 10. The user then calculates how much of the substance is desired to be dispensed and determines the indicia reading on the graduated scale which corresponds to the calculated amount. The container 10 is then grasped by the user and the spout 22 is positioned over the opening 14 through which the contents are to be dispensed. As the container 10 is tilted into a horizontal position, the spout 22 is caused to extend into the opening 14. The contents are caused to be dispensed from the container 10 as the container 10 is tilted further. As the container 10 is tilted, the second graduated scale 34 enters the line of sight of the user. The user may now measure the amount being dispensed by observing the decreasing level of substance within the container on the second graduated scale 34. When the level of substance observed matches the determined level, the user will tilt the container 10 back to the vertical position and thereby cease dispensing of the substance. The user is also able to determine when the container 10 is empty and can either be refilled or disposed of by viewing the first graduated scale 30. The cover 50 will now be placed to seal the spout 22 closed until the next desired use.
From the above description it can be seen that the graduated sight glass container of the present invention is able to overcome the shortcomings of prior art devices by providing a graduated sight glass container including a pour spout extending from a side thereof allowing the pour spout to be positioned close to a fluid receiving opening prior to pouring the contents of the container and thereby prevent spillage of the contents of the container. The graduated sight glass container may be made of a clear material allowing the user to view the contents therein and determine when the container is empty and includes a translucent graduated scale positioned on a side of the container allowing the user to accurately measure an amount of substance to be dispensed from and an amount of substance remaining in the container. The translucent graduated scale extends along the base of the container thereby providing the user with an accurate measurement as to the amount of substance remaining in the container during dispensing of the substance. The graduated sight glass container also has a rectangular shape without any protrusions thereby increasing the stackability of the container. Furthermore, the graduated sight glass container of the present invention is simple and easy to use and economical in cost to manufacture.
It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claims, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
